To avoid use errors when handling medical equipment, it is important to develop products with a high degree of usability. This can be achieved by performing usability evaluations in the product development process detect and mitigate potential problems. A commonly used method cognitive walkthrough (CW), but this shows three weaknesses: poor high-level perspective, insufficient categorisation detected problems, difficulties overviewing analytical results. paper presents further CW aim...

Automated Driver Assistance Systems (ADAS), which aim to enhance safety and comfort while driving, are becoming increasingly popular in vehicles today. However, ADAS not yet operative every situation due technical limitations, therefore do cover all driving situations, traffic, weather and/or road conditions. In order for drivers use these systems a safe manner, they need understand the different modes of operation, as well limitations systems, or will be able build appropriate trust...

The Technology Readiness Level or TRL, has a long history at NASA and American Department of Defence (DoD), when designing testing new technologies. Could this methodology be used in production system context? Due to the increased information complexity systems today technologies prototypes have developed tested more frequently. Cognitive automation strategies are becoming competitive benefit for companies that standardisation it comes prototyping testing. aim paper is show how TRL could...

Abstract Evaluation methods of today often focus on cognitive ergonomics (such as mental workload or usability) physical body posture). This article describes an analytical methodology a joint systematic search for potential deficiencies in the human–machine interaction; such high and workload, use errors, usability problems, ergonomic errors. The purpose with is to achieve more holistic evaluation approach make cost effective than when using separate aspects. task‐based, which makes it...

Abstract Aim This study identifies and compares perceptions of autonomous vehicle (AV) implementation among three Swedish stakeholder groups: Future Users , Urban Planners Developers. Method Semi-structured comparative focus groups were conducted separately with each the stakeholders transcripts analysed in broad themes using thematic analysis. Results Assumptions, hopes, concerns, direction development main that emerged from analysis . Assumptions included electrification vehicles, changes...

Musculoskeletal disorders (MSDs) are a common reason for health problems and sick leave in many professions. A work arena where MSDs have not been sufficiently studied is stable work. Here heavy repetitive tasks performed manually with old-fashioned working tools.The aim of this study was to use an analytical approach identify, evaluate grade ergonomic physical during daily activities horse stables relate these among the workers design tools.Three were problems; mucking out, sweeping bedding...

The benefits of involving users in a development process are well described. This paper describes procedure for using 2D and 3D models workplace design process, which is based on three rounds user studies within the maritime domain. includes various kinds that can be used order to elicit feedback cost-effective manner. Design teams greatly benefit from such mediating objects draw out users’ previous experiences. It was found different model types allow levels reflection questioning prospective users.

Workplace Ergonomics and Human Factors (E/HF) remains as relevant important ever to respond contemporary workplace design challenges. Therefore, E/HF expertise must be involved in early appropriate phases of the process, order leverage user needs requirements constrain proposed solution. In this decisions are made.The aim article is describe use a systems-theoretical framework guide collaborative design, focussing on planning documenting which activities should involve expertise.As...

The task of handling reach trucks frequently involves poor working postures. location the steering wheel in most is front operator which requires drivers to bend forward and stretch their hands for holding onto wheel. To overcome visibility restrictions, this posture aggravated by twisting bending torso sideways. This paper presents a usability study was conducted compare adoption ergonomic features new truck cabin with way they were intended be employed improving physical conditions....

Equipment used for high-risk sports, such as kitesurfing, needs to be efficient the intended use and user, thus meet mechanical demands provide sufficient safety. Accidents related kitesurfing occur, consequences are sometimes catastrophic. One important factor is equipment design, which can influence type number of injuries due insufficient safety systems. The aim this study was investigate how design affect issues from a usability perspective in relation task preparation. A focus group 6...

There is a need for appropriate evaluation methods to efficiently identify and counteract usability issues early in the development process. The aim of this study was investigate how product developers assessed new theoretical method identifying problems use errors. Two cases where had been applied were selected users them asked fill questionnaire then interviewed about their experiences using method. Overall, participants (students professionals) found useful outcome trustworthy. At same...

Abstract In any work system design intervention—for example, a physical workplace re‐design, process change, or an equipment upgrade—it is often emphasized how important it to involve stakeholders in the of analysis and design, gain their perspectives as input development, ensure future acceptance solution. While users artifact are most regarded being intervention, work‐system context there may be additional influential who influence negotiate intervention's outcomes, resource allocation,...

This study examined the physical demands involved in manual manure handling horse stables when using two different long-shafted work tools, a shavings fork and fork, investigated how variations shaft length affected workloads of user. The methods used were generic task specification (GTS) Jack human simulation system (JACK). In general, adding 10 cm to 125 existing gave highest reduction load on back, especially regarding compression forces, irrespective body height, sub-task technique....
